Two-transmitter wireless power transfer with LCL circuit for continuous power in dynamic charging

Wireless power transfer is a safe and convenient method for charging electric vehicles (EV). Dynamic charge can further reduce the needs of high capacity, heavy and costly batteries. Long transmitter coils provide steady power flow for certain distance. However coupling between the long coils with small coils is prone to field leakage and lower efficiency. Therefore, simultaneous two-transmitter method is proposed to emulate the long transmitter coils. LCL configuration is used for each transmitter to allows inverter sharing.
